Q2 Cost of Sales = Opening Inventory + (Purchases - Purchase Returns) + Carriage Inwards - Closing Inventory = $12,000 + ($ 85,000 - $3,000) +$ 2,000 - $15,000 =$ 12,000 + $82,000 +$ 2,000 - $15,000 =$ 81,000 [3] (1 mark for formula, 1 for correct net purchases, 1 for final answer)

Q3 Profit is understated. [1] (Closing inventory $\downarrow$ $\rightarrow$ COGS $\uparrow$ $\rightarrow$ Profit $\downarrow$ )

Q8 The estimated selling price in the ordinary course of business minus the estimated costs of completion and the estimated costs necessary to make the sale. [2]
